Method and system for determining height above ground using indirect information
First Claim
Patent Images
1. A method of furnishing an air traffic display on an aircraft, the method comprising:
- receiving Mode C transponder data from a first target aircraft, the received Mode C transponder data including pressure altitude information for the first target aircraft;
receiving traffic tracking data for a second target aircraft, the received traffic tracking data including pressure altitude information and an on-ground indication for the second target aircraft;
determining height above ground for the first target aircraft using the traffic tracking data from the second target aircraft; and
suppressing the display of the first target aircraft on the air traffic display based on the determined height above ground.

Abstract
Techniques and systems are described that allow an air traffic display and/or avionics system of an aircraft to display and/or warn a pilot of aircraft targets for air traffic proximate to the aircraft or to suppress the display of on-ground air traffic targets. In some implementations, an integrated avionics system can use indirect information to determine whether an individual aircraft traffic target is to be presented to a pilot. For example, the integrated avionics system can determine whether an aircraft target is in proximity to the ground based on traffic tracking data corresponding to other aircraft.
